PS 60W 24/48/60VDC HF
system power supply
The PS 60W 24/48/60VDC HF enables ex-
tended retentivity of the CPU's data work
memory.
In the event of the failure of the supply volt-
age, the PS 60W 24/48/60VDC HF supplies
sufficient power for the CPU to back up the
entire data work memory to the SIMATIC
memory card.
Time synchronization
For all applications which require the exact
time, update the time of the CPU using the
NTP procedure. This also automatically sets
the CPU time beyond subnet limits.

Reading out the identification
and maintenance data using
the Get_IM_Data instruction
With the Get_IM_Data instruction you can
read out the identification and maintenance
data of the modules without much program-
ming work.
With the Get_IM_Data instruction you can
access identification and maintenance data
(I&M) of a module in the user program. I&M
data is information saved in a module. This
allows you to
•
check the system configurations
•
react to hardware changes
•
react to hardware faults in the user pro-
gram.
Locating and fixing hardware errors is made
easier.
